We're dividing 87296455 by 223 
The aim is to understand the frequency of 223 in 87296455.

Moving on to step 1:
When dividing 8 by 223, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 223

Step 2:
When dividing 87 by 223, we get 0 with a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Fetch the next digit (2) from the dividend, attach it to 87 and continue: 872 / 223

Advancing to step 3:
The number 223 fits into 872 3 times, leaving a remainder of 203.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 669 from 872 to get 203.
Grab the next digit (9) from the dividend, add it to 203, then carry on: 2039 / 223

Going ahead to step 4:
223 goes into 2039 9 times with a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtract 2007 from 2039 to get 32.
Append the next digit (6) from the dividend to 32 and continue with: 326 / 223

Let's proceed to step 5:
223 can be fit into 326 1 times, resulting in a remainder of 103.
The number 1 becomes the next digit in our result. 
Result so far: 391.0
Subtracting 223 from 326 leaves us with 103.
Fetch the next digit (4) from the dividend, attach it to 103 and continue: 1034 / 223

Moving on to step 6:
If we divide 1034 by 223, we get 4 and a remainder of 142.
Use 4 as the next digit of our solution. 
Result so far: 3914.0
If we subtract 892 from 1034, we get 142.
Append the next digit (5) from the dividend to 142 and continue with: 1425 / 223

Advancing to step 7:
223 can be fit into 1425 6 times, resulting in a remainder of 87.
The number 6 becomes the next digit in our result. 
Result so far: 39146.0
Subtract 1338 from 1425 to get 87.
Bring next digit (5) of the dividend behind the 87 and repeat the process: 875 / 223

Moving on to step 8:
When dividing 875 by 223, we get 3 with a remainder of 206.
Put 3 as the next digit of the answer. 
Result so far: 391463.0
If we subtract 669 from 875, we get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 9:
2060 divided by 223 is 9 with a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 391463.9
Subtract 2007 from 2060 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 10:
If we divide 530 by 223, we get 2 and a remainder of 84.
The next digit of our result is 2. 
Result so far: 391463.92
The remainder is 84 after subtracting 446 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 11:
When dividing 840 by 223, we get 3 with a remainder of 171.
Write down 3 as next digit of the result. 
Result so far: 391463.923
Subtracting 669 from 840 leaves us with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Going ahead to step 12:
223 can be fit into 1710 7 times, resulting in a remainder of 149.
Use 7 as the next digit of our solution. 
Result so far: 391463.9237
Deduct 1561 from 1710 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 13:
The number 223 fits into 1490 6 times, leaving a remainder of 152.
The number 6 becomes the next digit in our result. 
Result so far: 391463.92376
If we take 1338 away from 1490, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 14:
1520 divided by 223 is 6 with a remainder of 182.
The number 6 becomes the next digit in our result. 
Result so far: 391463.923766
If we take 1338 away from 1520, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Our division results in 391463.923766 with a remaining 1.82e-05.
